Then not only custom, but also nature affirms that to do is more disgraceful than to suffer injustice, and that justice is equality.

Wronging others harms you first

We tend to think of injustice as something that happens to us—we're wronged, we suffer, and everyone agrees that's bad. But Plato flips this around in an unsettling way: actually committing injustice is worse than enduring it. This doesn't mean being victimized is fine. Rather, he's saying that when you wrong someone, you damage something fundamental in yourself. You become the kind of person who betrays their own standards.

This matters because we live in a culture that often rewards getting away with things. Cutting corners, taking credit that isn't yours, bending rules when no one's watching—these feel victimless or smart. But Plato suggests every time you do injustice, you're training yourself to be unjust. The person you're becoming is the real cost, not just the external consequences you might face.

The equality part adds another layer: true justice isn't about winning or losing, but about recognizing that other people deserve the same respect you demand for yourself. When we see someone else's interests as genuinely equal to our own, wronging them becomes almost unthinkable. It's not restraint born from fear of punishment. It's clarity about what we actually owe each other.
